Specification of Letters Patent.

Application filed July 7 1913. seriaino. 777,634.

1 h (iZZw/mmt may commit: y y i lle it known that l, lVILnmM: BmfLnig a citizen of the l'l'nited States, residing at Springfield. in the county Oil Clark and State of Ohio, have invented. certain new and useful Improvements in Balanced Vindow-Eiashes o'lt' specification.

My invention relates to the building arts and particularly to window construction and means For controlling the movable sashes thereof. While it especially designed for use in hicteries or :nulitorinm construe tions wherein are embodied windows of large area. it is equally a inglicahle to window sashes ol cinnparatively small size as employed in residences stores, vehicles, etc.

lhe object 0] the invention tosinn plify the structure as well as the means and mode o'l. operation of such devices, whereliy they will not only be cheapened inconstruction. hnt will be more ellicient in use, easily and quickly operated and unlikely to get out of repair.

The present constrilel'ion is designed to all'ord an in1ohstri'lcted window space of maximum extent and a variable sash there ,tlor adjustahly supported without the neeessity of fixed supporting bars or posts extended across the window space, which tend to obstruct the view or light, and which may be shifted to open the top and. bottonl oi the window space with miniinnn'l effort.

As belore stated the (mnstruction is especially designeifl for use in large buildings, :laclorics, anditorinms, etc, wherein the eneral use ol the metallic window sash and panes of glass at extreme thickness render the variable sashes quite heavynnd their ad justinenls slow and laborious. It is usual to divide such window sashes into separately adjustable units *otl. comparatively small area.

The construction forniing the subject matter hereof obviatesthe necessity of separate units of. sniallali'ea and enables a singrle unit of extreme size, even so long, as sev-v oral hundred feet, to be operated in a single body with eornparatireease. lVhile great ell'ort will he requiredto elevate a heavy which the flollowing is a body, to lift its center of gravity to a higher plane, onlya very small proportionate etfort, merely sullicient to overcome the inertia ol the body, will he required to move it, so

long as the center of gravity remains in a substantially horizontal. plane.

-With this in view there has been provided in the construction, a variable window sash the center of gravity of which moves in a substantially horizontal plane throughout the full degree of adjustment of the sash. lVhile in the past it has been a common exed.ient to support mo able sashes upon trunnions or vpivots coincident with the axis oltheir swinging movement sneh construction has been found undesirable due to the lni'oxiinity of posts or girders of the buildingstructnre, adjacent line shafting or 1n:-

chines when the windows are caused to swing inwarcL and to lack of space between adjacent buildings when swung outward.

'loprovide a balanced window sash operating through a shitting n'ioveinent whereby the major portion of the sash may be projected either within or without the building according to the design of the controldevices; which because o'l its balanced construction may be moved with mininunn eliort, is one of the n'iniarv objects of lh e n'esent invention. l Vith the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction and the parts and the combinations thereof and the mode of operation or their equivalents as hereinafterdescribed and set forth in the claims.

Referring to the drawings, Figure 1 is a perspective view of the assembled window sash and its supporting and controlling nannhers in closed position. Fig: 2 is a similar view of the window in open position. Figs. 3 and l are a transverse sectional view and a front elevation respec tively otthe construction shown in Figs.

land. 9. Figs. 5 and Gare a transverse sec-i tional view and a front elemtion respectivel n of aniodification of the former con-1 siruction in which the w ndow is supported pended upon the swinginglinks 12..

from below. Figs. 7 and S are a transverse sectional view and a front elevation respectively of the window arranged to be pro jected almost wholly outward as might be desirable to avoid a post or girder or some other object located in close proxin'iity to the window opening. ld-igs. 9 and 10 are transverse sectional views of the window construction as applied to an inclined window space such as are found in light domes, saw tooth roof constructions, etc.

Like parts are indicated by similar characters of refer .ice throughout the several views.

Inthe drawings 1 and 2 are longitudinal frame inenribers of the building structure, shown in the drawings. as angle bars and compricng the c; .p and sill respectively of the window opening. It is obvious that these members may be channel or eye beams or of other suitable shapes.

7 The variable sash comprises longitudinally disposed top and bottomrails 3 and 4 connected one with the other by transverse T shaped sash bars 5 arranged in parallel spaced relation upon the lateral which the glass rests. The glassis secured in position by means of putty, cement or by sealing in the usual manner. The particular construction of the window sash is not essential in the present invention, but any suitable construction which will meet the conditions and requirei'nents of use, may be employed.

Referring to Figs. 1 to l and Fig. 9 bracket arms 7 are secured at spaced intervals to the structural beam or bar 1 and project outward and downward therefrom. Pivoted at 8 to the lower ends of the bracket arms 7 are swinging links 9 of comparatively short length, the ends of which are pivotally connected at 10 to suitable lugs or cars carried upon the longitudinal top.

rail 3 of the sash. The bracket arms 7 project below the level of the top of the sash whereby the links 9 will extend upward from their pivotal connections 8 to their connection with the sash when the sash is in its closed position.

Pivoted at 11 to the ln'acket 7 at a point removed from the pivotal. connection 8 is asecond swinging link 12 of greater length than the link 9. At its opposite-end, the swinging link 12 is pivotallyconnected with ears ,or lugs 13 carried by the bottom rail 4c of the sash. The weight. of the sash is sus- Both links v9 and 12 being connected with the sash will be caused to move in unison but inas much as the links are pivoted to the bracket 7 at widely separated points 8 and 11, the upper and lower edges of the sash will be moved simultaneously through eccentric paths of different radii. The upper edge 3 ledges of of the sash will. move inward and downward tl'irough a path concentric with the pivotal point 8 of the link 9. The lower edge at of the sash will swing outward and upward through a path concentric with the pivotal connection 11 of'the link 12. The

links. 9 and 12 are so proportioned in relatially horizontal line indicated by dotted and dash lines in the several figures, the axis about which the sash swings being 00- incident with the center of gravity the sash will be balaruted, therefore requiring but little effort to produce its swinging movement. The sash being supported to move freely in a horizontal direction whereby the center of gravity travels in a substantially horizontal plane will necessitate but little effort to shift it laterally simultaneously with its swinging movement.

In Figs. 5, 6 and 10 there is shown a modification which is substantially a reversal of the construction heretofore described. In this form of device a strut 15, pivoted at 16 to a suitable lug or car upon the sill beam Qand at its upper end to a bracket 17 carried upon the top rail 3 of the sash is. substituted for the suspension link 12 of he previous construction. The sill beam 2 carries bracket arms 18 corresponding to the bracket arms 7 of the prior construction to which are pivoted short swinging links 19 pivotally connected at 20 to cars or lugs carried by the lower sash rail 1. Otherwise th construction is the same as that before described except that in this form of device the upper edge of the sash will describe an arc of greaterextent than the lower edge thereof. The center of gravity which is coincident with the axis about which the sash swings will in this case move in a substantially straight line exactly as before described. V

The construction shown in. Figs. 7 and 8 while embodying the same principles as before described, discloses certain stiuictural modifications .of the supporting bracket and swinging links and further illustrates an applicati on of the construction whereby the ma jor portion of the sash is swung outward in order that the uper edge thereof may avoid an obstruction such as the post 21 located in close proximity to the window opening In practice it has been found entirely feasible and practicable to construct such a etitl encd by interposed space blocks 24:.

Inasmuch as the path of" the pivotal point 10 concentric with the pivotal connections 8, the location of the latter point can. readily be determined by the usual ilnctllod of finding the center common to three or more points on an arc. It is obvioue that the operation may be rewho by assuming the location of the pivotal connection 8 and determining the locatioiro'l the connection 11.

Inthc drawings the each has been shown with i to weight equally distributed, where by the center oi? gravity and axis about which the each swings will coincide with thcniedial line; It is obvious however, that by making the eat-1h rail t heavier than the rail 3 or vice versa, or by locating weights :uljaceut to either edge the center of gravity ma be shifted toward the edge of the sash causing it to move through a different path of travel. Such distribution of weight may be utilized to cause the sash to assume a predetermined position when operated.
